Method for identifying signal input channel and TV set adopting same

Abstract

The invention is suitable for the technical field of TVs and provides a method for identifying a signal input channel and a TV set adopting the method. The TV set comprises a signal input channel, a signal detecting unit, an identifying signal producing unit and an MCU (Microprogrammed Control Unit), wherein the signal input channel has multiple paths which are respectively used for receiving input signals; the signal detecting unit is used for detecting whether the signal input channel has signal input or not; the recognizing signal producing unit is used for generating an identifying signal which corresponds to the signal input channel and transmitting the identifying signal corresponding to the signal channel with signal input to the MCU; and the MCU is used for identifying the identifying signal and judging the signal input channel corresponding to the identifying signal. The technical scheme can identifying the input channels of multiple paths of signals with same property, control the TV set to be directly switched to the corresponding signal channel according to an identification result, facilitates and simplifies for the operation of a user to the TV set, leads the TV set to be more user friendly and improves the user experience.

Description

Technical field [0001] The invention belongs to the field of television technology, and particularly relates to the technology of signal detection and control. Background technique [0002] The ever-increasing number of external signal input channels of TV sets puts forward higher requirements for the processing of its internal integrated circuits. For example, new LCD TVs usually support multiple AV signal inputs, and also support multiple high-definition signals (YPBPR) or standard definition (YCBCR). ) Signal input, plus existing computer signal (VGA), high-definition multimedia digital interface (HDMI) and other necessary interfaces for other functional modules. If these interfaces are directly connected to the main chip, it will greatly increase The design difficulty and manufacturing cost of the chip are not completely suitable for the product needs of different market positioning. Therefore, the existing video processing chip mostly selects these external input interfaces...
